ver 09-Jul-2020 Hydrogen Peroxide Material Compatibility Chart All wetted surfaces should be made of materials that are compatible with hydrogen peroxide. The wetted area or surface of a part, component, vessel or piping is a surface which is in permanent contact with or is permanently exposed to the process fluid (liquid or gas). Less than 8% concentration H2O2 is considered a non-hazardous substance. Typically encountered versions are baking soda-peroxide toothpaste (0.5%), contact lens sterilizer (2%), over-the-counter drug store Hydrogen Peroxide (3%), liquid detergent non-chlorine bleach (5%) and hair bleach (7.5%). At 8% to 28% H2O2 is rated as a Class 1 Oxidizer. At these concentrations H2O2 is usually encountered as a swimming pool chemical used for pool shock treatments. In the range of 28.1% to 52% concentrations, H2O2 is rated as a Class 2 Oxidizer, a Corrosive and a Class 1 Unstable (reactive) substance. At these concentrations, H2O2 is considered industrial strength grade. Concentrations from 52.1% to 91% are rated as Class 3 Oxidizers, Corrosive and Class 3 Unstable (reactive) substances. H2O2 at these concentrations are used for specialty chemical processes. At concentrations above 70%, H2O2 is usually designated as high-test peroxide (HTP). Concentrations of H2O2 greater than 91% are currently used as rocket propellant. At these concentrations, H2O2 is rated as a Class 4 Oxidizer, Corrosive and a Class 3 Unstable (reactive) substance.
